Column Studies for the Adsorption of Brilliant Green, Fast Green FCF and Phenol Red Dyes on De-Oiled Soya and Bottom Ash

Abstract

The adsorption of the brilliant green (BG), fast green FCF (FCF) and phenol red (PR) dyes over waste materials like bottom ash (BA) and de-oiled soya (DOS) was investigated. Subsequent desorption was carried out using a suitable eluent. The eluent emerging out of the column was analyzed spectrophotometerically. The percentage saturation of the columns were found to be brilliant green (99.39 and 99.43 %) phenol red (99.14 and 99.16 %) and for fast green FCF (98.94 and 98.38 %), for bottom ash and de-oiled soya, respectively. Percentage recovery in case of brilliant green-bottom ash and brilliant green-de-oiled soya was 76.22 and 88.89 %, which was about 64.09 and 98.02 % for fast green FCF-bottom ash and fast green FCF-de-oiled soya and 91.40 and 98.02 % recovery phenol red-bottom ash ad phenol red-de-oiled soya, respectively.
